This spherical roller bearing carries two symmetric rows of rollers guided on a solid inner ring with two outer ribs, running on a bore of 65.0 mm, an outside diameter of 120.0 mm and a width of 31.0 mm, with a net mass of 1.501 kg. The E1A design allows a limiting speed of 7000.0 1/min and a reference speed of 4200.0 1/min, with a machined brass cage (M) providing stable roller guidance at these speeds. The C3 radial internal clearance compensates for thermal expansion and interference fits, keeping the bearing free of excess preload during operation. The self-aligning outer ring raceway tolerates shaft deflection and misalignment, while the standard relubrication feature allows grease to be replenished through the bearing without dismounting it.
